MACHINE.

SPECIFICATION forming part of Letters Patent No. 292,355, dated January22, 1884. I i r Application'filed September 18, 18:3. (No model.)

To all whom it may concern: a

Be it known that I, GEORGE IV; RAYMOND, a citizen of the United States,residing at Illinois, have invented certain new and useful Improvementsin Ditching Machines; and I do declare the following to be a full,clear, and exact description of theinvention, such as will pertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

This invention relates to certain new and useful improvements inditching-machines; and it consists in the peculiar construction andarrangement of parts, as will be hereinafter more fully set forth andclaimed.

In the annexed drawings,'Figure 1 is'a longitudinal sectional view of myimproved The letter A represents the body or frame, of the machine,which is made of wood, and rests on the axles B B. The axles are provided with wheels 0 O, as shown.

B represents an iron frame-work or brace, which is secured to the underside of the frame, near its center, and passes around and in front thecross-piece A of the frame, formingaprojection or support, a, for thedraft-pin E. The

brace D is provided below the frame with two arms, b b, which diverge toeach side. and are bolted to the under sides of the framesor sidepieces, A, as shown.

Fis the king-bolt that passes through the cross-piece A, frame-work orbrace D, and axle B, and connects them securely together. The draft-pinE plays or is swiveled in the frame-work D, passing through a hole inthe part a, and also one in the lower part of the G is a knuckle-piece,having an eye through which the draft-pin E passes. This knuckle isadjustable on the draftpin, and when in position is held there by aset-screw, 0.

Letter '11 represents the plow-beam, connected to the fork of theknuckle-piece G by a pin, d, which allows the beam to be raised andlowered by means of a levcr,' I. The beam His provided or spread withtwo arms, e e, I

whichcurve' downward, and are fastened to either side of. the plow'J.These arms e a are made of steel, and are elastic and capable of beingspread, so that plows of differentwidths may be used. The plow J isscoop-shaped or concave in formand diamond pointed, with the bottom ator near the pointslightly curved upward, as shown in Fig. 1. The arms- 6e have attached to or cast 011 them two uprights or lugs, f f, throughwhich passes a rod, 9. To

this rod 9 issecured an arm, h, which is attaehed at its other end to arock-shaft, K, ex-I tending across the machine transversely, andjournaled in suitable boxes on the side pieces," A A, as shown in'Fig.2. Toone end of, this shaft K is attached the lever I, which works:

in a ratchet-arc, L, thus holding the plow at any desired height. Armsii are attached to each side of the plow or scoop J, and carry betweenthem a pulley, M, over which passes an endlessbelt earth-conveyer, 7..This conveyer is nearly as wide as the plow, and serves to carry off thesoil from the plow and conveyit to the dumpor chute N, at the rear ofthe mach'ine. A pulley, O, is journaled between two arms, Z Z, that arefastened to thesides of the plow. This pulley O is placed a properdistance above the pulley M, and carries a c011- veyer, m. Theconveyer70 has riveted to its edges thin pieces of copper or steel about twoinches wide and at short distances apart, their purpose being to preventthe dirt from falling off at the sides of thevbelt. Slats placedcrosswise on the conveyer 7c are not used for the reason that a scraperis to be adjusted to clean the conveyer when the soil is muddy. Overpulley 0 passes belt-conveyer m, of the same width as conveyer 7c, andtraveling parallel with and a short distance above conveyer k. Grossslats a n are placed on this conveyer m,

through which slats run vertical spring steel tines o 0, the object ofwhich tines is to seize upon chunks, sods, and hard clods'and assist incarrying them up the conveyer 7c. The

belts or conveyers k and m'pass over pulleys WI and 0, respectively,which are placed or j ournaled in a pulley-frame, P, at the rear of themachine, as seen in Fig. 1.

The letter Q represents two bars of iron or wood, one on each side ofconveyer k, and con necting the plow J and pulley-frame I and serving tokeep the convcyers taut. The pulleyframe P consists of two upright armspivoted on a shaft, R, which extends transversely across the rear of themachine and above the rear axle, B. The pulley-frame swings back andforth on the shaft R, to respond to the action of the lever I whenraising or lowering the plow. The dump N is inclined, and so formed witha double chute as to throw the dirt on both sides of the ditch made bythe plow; or the dump may be arranged to throw the soil on either sideof the ditch by means of an adjustable partition.

S is the driving wheel or gear, firmly bolted to the left hindtread-wheel, G, that engages with a fixed pinion, p, on the shaft R. Afixed pulley, 1', on the shaft R transmits motion by means of a belt orlink-chain, r, to a pulley, 8, on a shaft, t, journaled in thepulley-frame P. A pinion or gear, T, on the shaft tnieshes with agear-wheel, U, on a shaft, 11, above. The pulleys O and M, which arekeyed to the shafts u and 2, respectively, are thus caused to rotate anddrive the belts or conveyers k and m. To the front of the machine isattached a spring-seat, V, for use of the driver, who has control of thelever I.

In operating the machine the conveycrs 7.: and m, which carry off thesoil as it is cut by the plow, are raised and forced backward by meansof the bars Q Q at thesame time that the plow J is raised by means ofthe lever I, and vice versa.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a ditching-machine, the combination, with the adjustable plow J,having bifurcated beam H, of the conveyers k m, adjustable knuckle G,and draft-pin E, substantially as described.

2. In a ditching-machine, the combination,

with the adjustable plow J, of the conveyers m k, side bars, Q Q,pulley-frame P, swiveled on the shaft R, and suitable connecting andoperating mechanism, substantially as described.

3. In a ditching-machine, the combination, with the frame A A andframe-work D, of the draft-pin E, knuckle-piece G, plow-beam H, havingarms 0 c and uprights ff, rod 9, arm h,secured to said rod and torock-shaft K, lever I, ratchet-arc L, plow J, conveyers in m, pulleys OO and M M, pulley-frame P, dump N, gears U T, pulleys s a, belt r,pinion p, and driving-gear S, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. RAYMOND.
